Abstract
IP security is provided in a virtual private network using network address translation (NAT) by performing one or a combination of the four types of VPN NAT, including VPN NAT type 'a source-outbound' IP NAT, VPN NAT type 'b destination-outbound, VPN NAT type ‘c inbound-source' IP NAT, and VPN NAT type ‘d inbound-destination’ IP NAT. This involves dynamically generating NAT rules and associating them with the manual or dynamically generated (IKE) Security Associations, before beginning IP security that uses the Security Associations. Then, as IP Sec is performed on outbound and inbound datagrams, the NAT function is also performed.
